Problem
What route(s) do you think the first Americans (Paleoindians) used to enter the Americas? Was there more than one? Was one used more than the other? Was there only one major radiation of Anatomically Modern Homo sapiens from the Old World to the New World, or several major radiations? What influences did paleoclimate and paleogeography have? How is this reflected in the genomes of modern day indigenous (North and South) Americans? What are some examples of stone tool and other material technologies that enabled Anatomically Modern Homo sapiens to survive in the New World?
